AppRanks verdict
Generated from live marketplace data — refreshed daily
WHMCS is a well-rated Zendesk app with a limited review volume. It is listed in the Agent Productivity category on Zendesk Marketplace, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 34 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. The free tier lets you trial the entry feature set without committing a payment method. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical Zendesk Marketplace listing.

- +Free tier available — no card required to evaluate

About WHMCS
How WHMCS works
Show full descriptionShow less
Bring your WHMCS data into Zendesk and give your support teams instant access to the information they need without switching tools.
This app displays key customer details from your WHMCS directly in the Zendesk ticket sidebar. As soon as a ticket is opened, agents can view relevant client information and respond faster with full context.
With this WHMCS app, your teams can view the following information:
Customer details
Ordered products
Assigned domains
Due invoices
For a more advanced integration, we maintain a separate WHMCS module designed to:
Allow your customers to manage tickets in your WHMCS client area without the redirection to Zendesk
Offer Single Sign-On (SSO) between Zendesk and WHMCS
If you'd like to explore the full capabilities of this integration, you can find more details at: https://www.modulesgarden.com/products/whmcs/zendesk
Data Disclosure
This app accesses the client’s email address in order to identify the related customer record in the connected WHMCS instance.
For this purpose, the app sends the client's email address to the configured WHMCS endpoint together with the authentication data configured by the administrator for the integration, including a secure code and, if enabled, HTTP Basic Authentication credentials.
The app uses this data only to retrieve and display matching WHMCS customer information within the Zendesk sidebar, including customer details, products, domains, and due invoices.
The app does not independently store Zendesk user data or ticket data outside of Zendesk and the connected WHMCS service. Any storage, logging, or retention of data is subject to the customer's WHMCS environment, server configuration, and infrastructure.
